Title: Imaging apparatus and imaging lens
Inventor: TANAKA YOSHIHARU
IPC: H04N5/335
Filed: 2002-07-01
Abstract: <P>PROBLEM TO BE SOLVED: To provide an imaging apparatus capable of obtaining an image with optimum image quality in response to a particular operation setting.  <P>SOLUTION: A digital camera has a camera-shake correction function that can correct a shaken object image by moving a CCD 5 in response to vibration of the digital camera. When the camera-shake correction function is turned off, the center position SC of a shading characteristic formed via an imaging lens is made coincident with an image center position 5C. Further, when the camera-shake correction function is turned on, the center position CC of an image circle is made coincident with the image center position 5C. Thus, when the camera-shake correction function is turned off, a natural image wherein shading is symmetrically distributed in the image can be acquired while, when the camera-shake correction function is turned on, a moving marginal distance MA of the CCD 5 is uniformized in every direction and the image wherein the shake of the object image is effectively suppressed can be obtained.  <P>COPYRIGHT: (C)2004,JPO

Abstract: <P>PROBLEM TO BE SOLVED: To provide an expansion valve of constant flow rate not affected by the leakage of a refrigerant in a sliding part of a piston.  <P>SOLUTION: A piston 32 fixed to a shaft 25 of a solenoid is mounted on the way of a refrigerant passage where the refrigerant introduced to an refrigerant inlet 2 flows to a refrigerant outlet 3 through a main valve composed of a main valve seat 4 and a main valve element 5.
